I hear ya man. I'm not actively pursuing the record necessarily, just the biggest fish that I have access to. I firmly believe I have two lakes local to me (at least, maybe a couple more) that possess DD fish at certain points of the year. I have seen one fish in one of these lakes that I'd put a paycheck on it being 10 or slightly larger. So, they are here.
The main issue with a lot of northern guys is they are not actually fishing for THE big fish. They fish for 5 fish, they fish to catch something. Some guys will get "lucky". They don't commit to learning the water as it applies to the apex bass, studying where big fish should be and at what time of the year they should be there. They do not broaden their fishing base to include techniques that put you in a position to catch true trophy bass (comparable to your area). That's cool if that's what they are into, it's just not for me. I will happily forego 3, 4, 5lb fish in lieu of catching something truly noteworthy.
Like I said before. If you're not aiming high, you're gonna miss low.
